do modern linuxi not require a swap partition anymore these days ? O_o
Don't need one but they are recommended if you are using a lot of active data (running lots of memory demanding programs at once).
I'm pretty sure it's all covered by the linux install though (so no longer a manual process).

https://help.ubuntu.com/community/SwapFaqi heared from a friend i need atleast 2 GPU if i would use 3 monitors. i would like to have 2 coolers, dunno if it fits with the fans
2 GPU in crossfire yes (Think you can get up to 6 monitors with a top of the range single graphics card.. but it's a lot better with dual)
You can only have 1 CPU cooling unit not 2. For cooling it's mostly about the case. You need a fan intake at the front and a fan out take at the back, a CPU cooler and your graphics cards will come with their own fans also (this is minimum, some cases can have a lot more fans.) So if you want more cooling you have to pick a different case... Big cases with lots of fans is the coolest way to go.. but take up a lot of room and the more fans you have running the more noise it will make.
